Abstract

Despite extensive research into different pothole repair method, up to date, there is no research using the induction heating technology to address the pothole repair has been investigated. The utilization of induction heating with the innovative pothole repair materials is proposed in the current research, evaluated and compared to current patching materials. Binder pellets are composed of bitumen, steel wool and a protective shell to avoid them sticking to each other. Such pellets can be packed, stored, and transported like a simple aggregate. Once on-site, the required amount of pellets is heated and mixed with cold aggregates in a portable mixer with an electromagnetic induction generator. In this research, heating, volumetric and mechanical properties (indirect tensile, tensile and shear strength, as well as resistance to permanent deformation) of the resulting material were assessed and compared to conventional road repairing materials. Results of the use of the innovative materials showed excellent durability and performance; higher than a road repaired by cold mix asphalt and even similar to the performance of a road recently repaved.
